Halfway Between 81 and 771

When you ask "What number is halfway between 81 and 771?" we assume you mean the number in the exact middle of the two numbers on a number line, as illustrated below, where X=81 and Y=771.

Halfway Between Line

To find the number halfway between 81 and 771, we use the following formula:

(X + Y)/2 = Halfway Between

When we enter 81 and 771 into our formula, we get:

(81 + 771)/2 = 426

Thus, the number halfway between 81 and 771 is 426.

To check that our answer is correct, we subtract 81 from 426 and subtract 426 from 771 and compare the two numbers:

426 - 81 = 345
771 - 426 = 345

As you can see, the halfway number is 345 higher than 81 and 345 lower than 771. Therefore, our halfway between answer of 426 above is correct.
